In 1835, Lafayette, too soon familiar with violence, housed a fort that held Cherokee people until their forced removal west, and then, in 1863, Walker County witnessed 34,000 Union and Confederate deaths at Chickamauga, a battle often considered the second bloodiest of the Civil War.
Re: After Provisional Patent Expires... You should get the provisional filed within that 12 month window. If you forget or unintentionally did not file the non-provisional you can petition the patent office for an extra 2 months but the petition fee starts at $800.
This occurs when the claims of a patent are obvious from the claims of a commonly owned earlier issued patent, such as a parent application of a continuation application. Sometimes (but not always) this is also marked by an asterisk after the patent issue date.
